Hello - We have a GWL10US with a Controller Board that has a couple of blown out components. I’d like to replace these components (I’m comfortable soldering), but since they are burned out I cannot read their part numbers. Attached is a photo. Does anyone have access to schematics and/or parts list for this controller board? I would much rather try repairing this board than spending $200 on a 10-year old machine.

FWIW, here’s a summary of the troubleshooting steps that were taken:

The GWL10 stops in the middle of a normal wash cycle and beeps continuously once per second. The fault code on the display seems to be 00110011. According to the Service Manual, this code means "Diverter valve timeout fault."

I disconnected the Diverter Valve and measured 1.9KOhms across its terminals. Since this is not an open circuit, I am assuming the valve is ok.

I then reconnected the terminals, went into diagnostic mode, and used the "Delicate" button to turn the Diverter Valve on and off. With a voltmeter on the connected terminals of the Diverter Valve, I saw no change in voltage (DC or AC) when I pressed the Delicate button over and over again.

I then did a sanity check to see if the Diverter ever diverts:

Got into Diagnostics mode.

Pushed the Temp Down button to get some water in the tub.

Pushed the Delicate button to turn the diverter ON, at which point the Delicate light went ON and stayed ON.

Waited a couple of minutes.

Pushed the Regular button to turn the pump ON, at which point water was pumped to the DRAIN (not recirculated).

Pushed the Delicate button again to turn the diverter OFF, at which point the Delicate light went OFF.

Waited 4-5 minutes.

Pushed the Regular button to turn the pump ON, at which point water was pumped to the DRAIN (not recirculated) again.

Before pulling the Controller Board, I checked all of the other components (valves, pump motor, etc.), and all resistance measurements checked ok. So, I decided to open up the controller module. Sure enough, I can see two components that got smoked. Once is clearly a MOSFET, and although the part number is pretty much blown away, I think there's enough there for me to tell that it is the same as a nearby part, which is STD2NC60.

But the other part is not so easy. It looks like it could be a transistor, with 2 pins on one side and 1 on the other. I think I can make out "XG..." on it, which doesn't match up with any other 3-pin device on the board. So, I'm stuck.

I then reconnected the terminals, went into diagnostic mode, and used the "Delicate" button to turn the Diverter Valve on and off (at least, that's what I hoped I was doing, based on info in the Service Manual). With a voltmeter on the connected terminals of the Diverter Valve, I saw no change in voltage (DC or AC) when I pressed the Delicate button over and over again.

So...it seems like the finger is pointing at the Motor Controller Module, but I sure what love it if someone experienced with these machines could help me confirm this diagnosis. $180 is a lot to spend without being sure...
